What is the minimum order quantity for custom onesies, and is it firm per style or color?

MOQs typically start at 25 units per style-color combination. The number is firm at the style-color level because each colorway requires its own dye lot and cut setup. Your production team can walk you through how to structure a multi-style drop to make the most of your order.

How much does a onesie sample cost, and how long does it take to receive?

Sample cost depends on the complexity of your design - materials like bamboo or seamless knit, plus any decoration such as custom zipper pulls or woven labels, all factor in. Submit a brief and your team will return sample pricing and a timeline, which usually runs 2-3 weeks. This is separate from your full production lead time.

What is the production lead time for a custom onesie order?

A typical production run - say 250 long-sleeve cotton onesies with screen print and woven labels - generally ships in 4-6 weeks after sample approval. Lead times can shift depending on material, decoration complexity, and factory capacity, so your production team confirms an exact schedule once the brief is locked.

Do you offer tiered pricing for onesies at different quantities?

Yes. Pricing tiers exist at the 25, 50, 100, 250, and 500-unit break points. Per-unit cost drops as volume increases. Submit a brief with your specs - fabric, decoration, packaging - and your team returns a tiered quote so you can plan your drop at the right quantity.

What does private label and white label onesie production include?

Private label scope covers woven labels, hangtags, screen-printed care info, custom zipper pulls, and custom packaging such as branded boxes, polybags, or mailers. You can bundle everything for a fully branded white label onesie or choose elements a la carte. Your production team builds it all into one brief.

Can you source materials from a brief, or do I need a tech pack with named fabrics?

Either works. If you have a tech pack that specifies a named fabric, the team matches it from the factory network. If you are starting from a brief - for example, 'soft breathable bamboo for a baby onesie' - your team recommends the right material and weight from options like cotton, flannel, seamless knit, or bamboo, then sends swatches for approval.

Can you grade patterns from my measurements instead of stock templates?

Absolutely. Share your custom size specs and the team builds a grading set from your measurements, not generic stock blocks. This is especially useful for plus size or baby onesies where fit accuracy matters. Grading is finalized during the sample stage before production begins.

Can I mix sizes and colors within one MOQ for onesies?

Yes. You can split sizes and colors within a single style's MOQ. For example, a 50-unit crew neck onesie order could include a mix of sizes across two colorways. Your production team helps you map out the size-color matrix so the manufacturer can cut efficiently.

What decoration methods are available for custom onesies?

Options from the factory network include screen print for durable spot-colour graphics, DTG for full-colour digital artwork, woven labels for branded neck and care labeling, screen-printed care info, custom zipper pulls, and custom packaging. Your team recommends the best combination based on your design brief and target audience - whether that is baby, men's, or plus size onesies.
